4 kW Solar PV System Scotland

For a long time now a 4 kW solar PV system has been the most commonly known and installed domestic solar panel solution in the Scotland. 

Much of this has to do with most homes in Scotland being a similar size and layout, therefore the roof space often is perfectly suited to a 4kW system.

It also comes down to peoples energy usage and what the average home needs to cover those costs.

In 2024 however, solar panels have come a long way! For one, the space required for a 4kW PV system has reduced, with each panel these days having more capacity for producing more power, the standard being 430 watts. 

In the not too distant past, panels only had half of this output or even less! In simple terms, this means in most cases, what used to be a 16 panel system is now an 8 panel system. 

That is not always an exact science, but it’s safe to say your roof can now hold way more kW per square metre than ever before!

Modern 8 panel 4kW PV System

Shown below are panels installed in 2024 with higher power output of 510 watts, meaning an 8 panel PV system will see an expected return of 4kW over the course of the year. This particular installation was in Stirling, and as you can see the more powerful panels are useful with more limited roof space available.

Traditional 16 panel 4kW PV System

Now an example of the more commonly known 16 panel 4kW PV system, that’s been installed on homes in Scotland for decades. This was actually a more recent installation, however, the customer opted for the lower cost and lower output panels to save money. A solar battery storage system was also installed to maximise on returns.
